Labcorp Genetics (formerly Invitae), Labcorp RCV002814667 SCV003202840 uncertain significance Progressive sclerosing poliodystrophy 2022-08-19 criteria provided, single submitter clinical testing In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with POLG-related conditions. This variant is present in population databases (rs750555988, gnomAD 0.0009%). This sequence change replaces glutamine, which is neutral and polar, with histidine, which is basic and polar, at codon 77 of the POLG protein (p.Gln77His).
